For example, arsenic is ion-implanted in an N-cannel MOSFET region under the conditions of 50 keV and 1 to 3×10<15> cm<-2> and for example, BF2 is ion-implanted in a P-channel MOSFET region on the condition of 30 keV and 1 to 3×10<15> cm<-2> . A heat treatment of a silicon substrate 101 is performed in a hydrogen atmosphere at 500 deg.C. The reactivity of hydrogen to fluorine is high, and an HF is formed by the heat treatment in the hydrogen atmsphere at a melting point of -83.7 deg.C of HF.  In the dependence of the yield of a gate oxide film due to the initial defective withstand voltage of a P-type MOS gate on a hydrogen heat treatment temperature, the substrate 101 is heat-treated in a hydrogen atmosphere at a temperature higher than the boiling point of 262 deg.C of the HF, whereby the fluorine concentration in the gate oxide film is reduced with the vapor of the HF from 400 deg.C or higher, and the yield of the gate oxide film is modified.

Title: Automatic document density detecting device
Inventor: HONDA MITSUNOBU
IPC: G03G15/04
Filed: 1988-12-22
Abstract: PURPOSE:To miniaturize a copying machine main body by installing a concave lens between a document and a document density detecting (EE) sensor. CONSTITUTION:The EE sensor 7 is installed below the front surface of a document glass 3, and the concave lens 8 is installed above the sensor. The EE sensor 7 and the concave lens 8 are fixed with a holder 9. The concave lens 8 compresses a picture on the surface of the document 4 as a virtual image to form an image, whereby the effective density reading width on the surface of the document 4 can be increased. Compared with a detecting device which employs no concave lens 8, a wide effective reading width can be obtained at the distance between the surface of the document 4 and the EE sensor 7, and consequently the distance between the surface of the document 4 and the EE sensor 7 can be minimized. Thus, the copying machine can be miniaturized.

Title: Cylindrical electromagnetic wave absorber
Inventor: HASHIMOTO OSAMU
IPC: H01Q17/00
Filed: 1989-12-14
Abstract: PURPOSE:To obtain the optimum cylindrical electromagnetic wave absorbers by determining the material constants of loss materials from nonreflective curves for cylinders. CONSTITUTION:Cylindrical electromagnetic wave absorbers are made with loss materials formed into cylinders wherein epoxy resin and carbon particles are mixed with fibers, and the material constants of the loss materials are determined by nonreflective curves for cylinders. Namely nonreflective curves for cylinders obtained using an analysis method are used in the case of designing these cylindrical electromagnetic wave absorbers. Namely the use of the nonreflective curves for cylinders having various kinds of diameters makes it possible to obtain cylindrical electromagnetic wave absorbers for each kind of diameter and polarized wave. In this way, the cylindrical formation of the absorbers makes it possible to fit them to cylindrical substances to be fitted. Moreover it becomes possible to obtain much larger wave absorbing quantity than the case where a platetype electromagnetic wave absorber is bent and used.

Title: Method and device for reducing occurrence of risk of nipping between automatic doors
Inventor: MAAKU HEKURAA
IPC: E05F15/10
Filed: 1990-11-27
Abstract: PURPOSE: To enhance the safety by allowing the door stop and reverse motion to be worked by an external interferential force and actuating the start in the full run of the door which is going to shut with an adjusting error exceeding the prescribed allowable value. CONSTITUTION: If the specified stop time for a door has elapsed and no obstacle is sensed, the door shutting is started. From a target valve producer 3.5, a target value Vref is fed to a first comparator 3.1, while the actual value Vist is fed from a digital tachometer 2.2, and an adjusting error dV is generated from the two values. The error dV is determined by a limit comparator 3.7, and if dV<dVmax, a compensation value Vk is added to dV in a second comparator 3.2 and fed to an adjuster 3.8. In compliance with the signal from the adjuster 3.8, an electronic exchange system 2.4 drives a DC motor 2.1 so that the door is shut. If any obstacle is sensed, dV>dVmax is established, and the motor 2.1 is braked so that the door is opened.

Abstract: PURPOSE:To prevent trouble following speeding-up of the rotation of a disk by fitting plural kinds of magnetic disks all at the same pitch (height) and enabling recording and reproducing any of the disks without changing the pitch (height). CONSTITUTION:The disks 8-10 are layered via spacers around a spindle motor 4 and tightened by a clamp 11. The disks 8-10 can be fitted alternately with their different diameters.
